3 SHEETSA-SHEET 3- INVENTOR v faim AWGRNEY LIMITEE ySTATES JOHN J; EAGAN, or` SAN FRANCISCO, CALIFORNIA CONCRETE SHIP CONSTRUC'lICll.\T`

T o all whom it 'may concern.' y. Be it known that I, JOHN J. EAGAN, a citi- `zen of the United States, residing at the a concrete hull having improved means ofV reinforcement,so as to give the same greater strength than heretofore known, and my invention consists in the novel arrangement and combination of parts shown inthe accompanying drawings,VA described in the following specification and particularlyV pointed out and claimed in the appended claims. A

Referring to theV accompanying drawings lllustratingmyv invention, so that one skilled.

in the art to which the invention pertains may make the same, Figure 1 isa side view of the ship embodying my invention, with parts-omitted, and parts of said view being broken away to show certain features of the construction; Fig. 2 is a'transverse vertical section of 'the hull; Fig.v 3fis-an enlarged detail view of the partition in and side of the hull, and Fig. 4 is a detail showing in what manner the semi-circular tubes hereinafter mentioned are fastened to the transverse ribs.

Inthe figures A represents a concrete ves-l Running transversely of the vessel at cer-` tain intervals and passing through the central tubular member at the bottom are ribs 9, the same being bent up to form side supports for the vessel. Semi-cylindrical reinforcing elements 8 are placed at certain intervals on Outer side of ribs 9 and are suit- Speeication of Letters Patent.

ably tied thereto, the same running longiy l tudinally of the shell from bow toV sternV for the purpose of forming a rigid structure the full length ofthe ship and said ktubes contain cables- 10 anchored in the bow and stern for supporting and strengthening saidv cables. lThe hull of the vessel is further supported by tubular vertical braces 11 secured in ribs 9 at the bottom of the said hull and upwardly in cross-tube 13, whereby the upper concrete .wall 14 of the bottom 1s supported. By means of the concrete walls 14' and 22 the shell inclosing compartments 12'is formed at the bottom, the dots ngge figures' indicating concrete as shown At certain intervals and spaced'from each other are columns'15 mounted in and cou-A pled centrallyV through the vessel as shown to support the upper and lower decks, 18,l

and the same are reinforced by'means of transverse tubes 16 connected to said ceneVv tral .columns 15 and at their ends secured to-the rlbs 9.

vThe decks and bottoms have reinforcing tubes 17, running longitudinally throughthe vessel and suitably secured to brace transv verse members 39. The transverse Vmembers 9 have ties 23 preferably ofwir'e, which encir-y cle the same and vare securedfto tubes 8, one

of which so securedy being shownin Fig. 4.'

rFubular members 24 run transversely in the A partitions shownandthe ends thereof are secured in verticall channel bars 26, and are suitably spaced''by' means of surrounding 4connected* wires `25. In the construction l use slip joints, which prefer to hold in position by means of pins running through,y

the same as shown at 20. Also in the construction wire meshv is placed in the hull of the'vesselas shown in Figs.'1, 2 and 3, being marked 21, and the same is advantageous as a reinforcement. I prefer to lill the tubular members forming the frame of the vessel Y together Ywith the bottom and sides of the hull with concrete so as to give the same the utmost strength.v It will be understood that the tubular members shown and described will be made in sections and have suitable joints for connecting thesame, and that the otherparts of the framework will besuitably bolted together so as to give the same the necessary rigidity.

Although I have shown and described the preferred form of my invention, the same may be modified, and therefore I claim all modifications of said invention which 'may fall within its spirit and scope.

I claim:

1. In a concrete vessel the framework consisting of U-shaped ribs for the` bottom and sides ofsaid vessel, cross-ribs connected to said Ushaped ribs and supporting the decks, pillars between and connected to said cross-ribs, a plurality of pillars between and connected to the lowermost of said crossribs and the bottom of said U-shaped ribs,

hollow members in Contact with the outer surface of said U-shaped ribs, cablesv extending through-said hollow members and secured to the ends of said vessel and wire mesh covering said hollow members.

2. In a concrete vessel the framework consisting of U-shaped ribs for the bottomV and sides of said vessel, cross-ribs connected to said U-shaped ribs and supporting the decks,

pillars between and connected to said crossribs, pillars between and connected to the lowermost of saidcross-ribs and the bottomY kpillars between and connected to said cross- Y ribs, pillarsl between and connected to the .i lowermost of said ycross-ribs and the bottom of said U-shaped-ribs,y hollow members in contact with the outer surface of said U- shaped ribs, cablesextending through y. said hollow members and secured to the ends of the vessel, wire meshcovering said hollow members, a plurality of equidistant crosstubes supported between said pillars and between said cross-ribs `and pillars nearest thereto, and a centrally placed bent up member forming the keel and front and rear ymain posts of the Vessel and having a cable extending therethrough. 4. In a concrete Vessel the framework consaid U-shaped ribs and supporting the decks, pillars between and connected to said crossribs, pillars between and connected to the lowermost of said cross-'ribs and the bottom 'of said VU-shaped ribs, Vhollow members in contact with the outerv surface of said U- shaped ribs, cables extending through said sisting of U-shaped ribs for the bottom and Y sides of the Vessel, cross-ribs connected to y hollow members and secured to the end'sof' Y the vessel, wire meshf covering said' hollow members, a plurality of cross-tubes support ed between said :pillars and between said cross-ribs and pillars nearest thereto, a centrally placed bent up member forming the A i keel and front and rear main posts, and tubing extending through the decks and wire mesh upon said tubing. n

sisting of Ushaped ribs for the bottom'and sides of said Vessel, `cross-ribs connected to said U-shaped`ribs and supporting theidecks, pillars between yandV connected to said crossf ribs, pillars between vand' rconnected to they lowermost of said cross-ribsand the bottom of said ULShaped'ribs, hollow members se,V 'I cured outwardly to said Ueshaped ribs, and

cables extendingY through saidv hollow Vmem-V bersand-secured tothe endsV ofthe Vessel. Y i i' 6.- InV combination with the transversere` inforcements Vof a; concrete ship, hollowA o. In a concrete vessel the framework con Y Y members in contact with 'the outside of the transverse reinforcements, .cablesy extending fromv end to end of thefvessel and secured theretoy vand incased in thehollow members and wire mesh covering the hollow members.v Y
